@tutti HEMON EIOIILER, Or `New LISBON, WISCONSIN. Letters Patent No. 87,48'1, datedV March 2, 1869.

The Schedule referred to in these Letters Patent and making of the mu.

To all whom 'it may concern:

Beit known that I, HEMON EIOHLER, of New Lisbon, in the county of Juneau, and State of Wisconsin, have invented certain new and useful Improvements in Leather-Cutting Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur. v

To enable others skilledin the art to construct and use my invention, I will proceed to describe it.

This invention relates to machines. for shaving or.

splitting leather, and consists in a novel arrangement of deviceswhereby a machine is produced that will shave orsplit leather to' any required thiuness, quickly, and ,without Waste.

Figure l is a vertical cross-section through my machine, on the line xx of ig..2.

Figure 2 a front elevation of the machine. l

The machine consists of an upright frame, A, hav ingsecured to it the stationary knife C, and provided with the rollers D and E, the former being located across the machine, directly under the edge of the aforesaid knife C, and thelatter mounted in the lower .end of a swinging frame, B, abovethe knife O.

The leather to b e operated upon is passed between the two.` rollers, and against the edge of the knife, as

l shown by the red lines in iig. 1, the body of the leather or valuable portion passingthrough, under the knife,

` between it and the rollerD, While the surplus portion taken oil, will pass above.

To compensate for the inequalities in the thickness of the leather, I mount the upper roller E in boxes el sliding up and down in slots inthe lower end of the frame B, and' secure to said 'frame a spring, F,aboye the said roller, and having one end bearing'upon top `of each of theboxes d, thus, while always' holding the roller down firmly upon the leather, allowing it to yield and rise when the leather is-very thick at anypoint.

When leather is to be presentedto the action of the knife, the frame B may be swung out, so as to throw its roller E back, as shown in red lines in lig-1,

thus permitting the leather to be adjusted against the knife as desired, after which the frameis brought down, and being pivoted, as aforesaid, presses the roller E down upon the leather with great force; and the Inore the strain brought upon the leather to draw it through,

the greater the pressure down upon it. Thus the leather is cut to a uniform thickness throughout.

'Ifo provide for cutting leather to any requisite thick?` 4 ness, I mount the lower roller D in adjustable boxes '0, playing in vertical slots in the main frame A, and

provide a bar, G, in shape similar to two wedges, connected end to end, and facing in the saine direction, and locate this bar across in the main frame, under the boxes c, in su'ch a manner that by moving the said bar in one direction or the other, the roller will be raised or lowered, both ends alike, all as'clearly shown in figs. 1 and 2; l

One end of this bar extends outa considerable distance onv one side ot the machine, and has fashioned upon it a handle, t, for convenience in operating it.

To prevent the frame B from swinging-through, or the roller-E from coming lin contact with the-edge of the knife, VI place, across the frame B, a bar, b, with its ends projecting beyond the sides of said frame, as shown by the dotted lines in tig. 2, and which, when the frame B has reached a perpendicular position, strikes against the main frame A, and prevents its furthermovement.

By this means I am enabled to make a machine specially, adapted to thev wants of harness-makers, and similar workers in leather, that is simple, cheap, and 'eiiicient Having thus described my invention,

What I claim, is-

1. A' leather-shaving machine, consisting of the sta` i,

tionary knife G, the adj nstable roller D, and the roller E, mounted in a swinging frame, substantially as here- I in described.

2. In colnbinatipn with the adjustable roller D, the y; wedge G, arranged to"operate Substantially as set forth.
